CDV Series Direct Vent Gas Fireplace
20010175
A hearth is not mandatory but is recommended for
aesthetic purposes. We recommend a noncombustible
hearth which projects out 12” (305 mm) or more from
the front of the fireplace.
Cold climate installation recommendation:
When installing this unit against a
non-insulated exterior wall or chase,
it is mandatory that the outer walls
be insulated to conform to applicable
insulation codes.
Hearth
Framing and Finishing
Check fireplace to make sure it is levelled
and properly positioned.
To mount the appliance:
1. Choose the location.
2. This unit comes with four (4) flanges pre-mounted
on both sides of the fireplace to allow two different
drywall thicknesses to be used. Flange “A” is for 1/2”
drywall while flange “B” is for 5/8” drywall.
3. Bend the desired flanges out 90° on both sides of
the fireplace. Slide the fireplace into the framed
opening until the flanges contact the front surfaces
of the framing. Level the unit and secure it firmly in
place.
4. The standoffs are adjustable for different drywall
thicknesses. The unit is shipped from the factory at
1/2” (13 mm). Loosen the four (4) screws securing
each standoff to the top of the fireplace. Slide the
standoff back. Tighten the screws. This yields a 5/8”
(16 mm) thick drywall space. Removing the standoff
and having the tabs on the standoff face the rear of
the unit yields a 3/4” (19 mm) drywall space. (Fig. 4)
NOTE: Drywall must stop at standoffs and not touch
top of unit.
Hood Installation
CAUTION: Hood MUST be permanently installed.
1. Remove top louvre. Carefully remove hood from
inside top louvre opening.
2. Remove three (3) sheet metal screws in bottom
flange of fireplace surround top.
3. Install the hood by aligning the three holes in bottom
flange of fireplace surround top. (Fig. 4a)
4. Secure hood to bottom flange of fireplace surround
top using three screws removed in Step 2. (Fig. 4a)
5. Carefully remove protectors under the relief plates
on top of the firebox.
